Having frizz-prone hair I'm a big fan of serums. That said, not all have the desired effect – some are too gloopy and weigh my hair down making it feel limp and a bit greasy. When I received a full sized Dr Organic Argan Oil Hair Treatment Serum in the Latest in Beauty CEW box I had high hopes. I was not disappointed. Quite simply this is the best hair serum I've ever used. It makes my hair soft and shiny without making it feel heavy or lank. In fact I don't need or want to use much hairspray with this serum because it tames my hair and seems to help keep it in place by getting rid of the fluffy and flyaway texture. Then there's the smell. Packed full of organic essential oils and fruit extracts it smells divine. It reminds me of an expensive spa treatment and leaves a lovely lingering scent on my hair all day. It has quite a spicy aroma due to the clove and cinnamon oils which blend well with the geranium, lemon peel, patchouli, rosewood and wild mint oils. I love this serum and having tried quite a few over the years in the search for the perfect hair product, I can safely say I've found it with this. You can find it at Holland and Barrett for £14.99 for a 100ml bottle, but you can buy two for £22.48. There are lots of other products in the Dr Organic range that I can't wait to try.
